We report recent flora of vascular plants in Mt. Soyo and compare it with previously reported floras by Lee and Yim (2002), Jang et al. (1999) and Kim and Han (2000). Fieldwork was investigated from April to October in 2007, from April to October in 2012, and supplemented by photos taken from 2003 to 2012. As a result, Vascular plants based on voucher specimens were summarized as 564 taxa, including 102 families, 331 genera, 493 species, 4 subspecies, 54 varieties, and 13 forms. Among the investigated 564 taxa, 15 Korean endemic species, 75 floristic regional indicator plants by the Ministry of the Environment were also included, 16 rare plants, and 29 naturalized plants. Growth overall plant species, Korean endemic plants, specially designated plants and rare plants was decrease then Lee and Yim (2002) but naturalized plants was increase. This result is due to human intervention, such as construction of roads, parking and so many hikers. In addition, one of the effects of heavy rains. We need to the ecological monitoring and regulation of hikers for the preservation of plant species diversity in Mt. Soyo.

The aim this study is to establish the floristic composition of vascular plants of Mt. Gwangdeok. The survey was performed 12 times from May to November in 2007 and April to November in 2011.

To address infra-specific relationships of Lilium cernuum Kom., and to provide the fundamental information for developing new horticultural variations, we analyzed the morphology of individuals in natural populations. It observed the external form of L. cernuum Kom., and described through dividing by each type according to a form, number and length in each organ, to distribution aspect of prop roots, and to appearance of spot in perianth lobe. Also, it described after observing the internal form and structure in each organ. As for analysis of main ingredient (PCA) by character in L. cernuum Kom., as a result of carrying out analysis of main ingredient in order to examine the appearance of being available for habitat-based distinction in L. cernuum Kom. by selecting 3 traits (length in upper leaf, length in lower leaf, length in scape), which show difference by region out of the quantitative joint characters in the selected individual, 3 wide-area groups were mutually overlapped. Thus, the group-based difference was difficult to be found. However, the following tendency could be found. In other words, as the group of L. cernuum Kom. in the northern area moves south along the Taebaek mountain range, the tendency was indicated that the lower to the Nakdong-jeongmaek leads to getting shorter in scape, to getting longer in the upper leaf, and to get shorter and then longer in the lower leaf. As another group goes down by diverging from the Taebaek mountain range to the Sobaek Mountains, the tendency was indicated that the scape gets longer and that length in the upper and lower leaves gets shorter.

This study was carried out to investigate the flora of Icheon-si (Gyeonggi-do). This work was investigated during the April to November in 2011. Some areas 2002, 2004, 2007 collected data were used. Vascular plants based on voucher specimens were summarized as 547 taxa, including 99 families, 313 genera, 475 species, 4 subspecies, 58 varieties, and 10 forms. Among the investigated 547 taxa, 6 Korean endemic species, 7 rare plants and 43 specially designated plants by the Ministry of the Environment were also included. A naturalized plants were 47 species, correspond to 14.6% of totaling 321 species appeared in South Korea.

As a endangered species designated by the Ministry of Environment of Korea, we report Millettia japonica (grade II) in this region.

This study was carried out to classify the regional folk plants in northern area of Gyeonggi-do. According to the survey results from 238 survey sheets of 223 residents at 65 places of 11 counties and cities from March to October, 2010, the folk plants in north of Gyeonggi-do consisted of a total 238 taxa; 84 families, 194 genera, 207 species, 3 subspecies, 26 varieties, and 2 form. The use by its usage was: 146 taxa; edible, 93 taxa; medicinal, 7 taxa; dye, 3 taxa; aroma, 4 taxa; spice, 4 taxa; ornamental, 12 taxa; fiber, 6 taxa; oil, 51 taxa; others, respectively, so the edible use is the highest. The most useful part was the leaf, followed by root and fruit. The consistency comparison between the scientific name and the local name was the lowest in 40's.
